Problems solved by technology

So far, because the network side cannot accurately know the coverage level and location of the terminal equipment in idle mode, the paging message can only be transmitted independently in multiple cells according to the number of repetitions corresponding to the maximum coverage level, which leads to relatively large Large downlink resource overhead

Embodiment 1

[0054] This embodiment provides a paging method executed on the first transmission node.

[0055] In this embodiment, the first transmission node sends the same paging configuration information and paging indication information to at least one second transmission node. In other words, in this embodiment, the paging configuration information and the paging indication information sent by the first transmission node to at least one second transmission node are the same.

[0056] The paging configuration information includes at least one of the following information: paging cycle, candidate time-frequency position, transmission block size, modulation mode, resource allocation, repeated transmission times, cyclic prefix (Cyclic Prefix, CP for short) type, transmission mode and scrambling logo.

[0057] The paging indication information includes at least the following information: an identifier of the third transmission node. The third transmission node is the transmission node th...

Embodiment 2

[0064] This embodiment provides a paging method executed on the second transmission node. figure 1 is a flow chart of the paging method according to the second embodiment of the present invention.

[0065] Step S110, receiving paging configuration information and paging indication information sent by the first transmission node.

[0066] The paging configuration information includes at least one of the following information: paging cycle, candidate time-frequency position, transport block size, modulation mode, resource allocation, repeated transmission times, CP type of cyclic prefix, transmission mode and scrambling identifier.

[0067] The paging indication information includes at least the following information: the identity of the third transmission node. Wherein, the identifier of the third transmission node is one or more.

[0068] Step S120, sending the paging configuration information to the third transmission node.

[0069] Step S130: Send a paging message to the ...

Embodiment 3

[0127] This embodiment provides a paging method performed on a third transmission node, Figure 4 is a flow chart of the paging method according to the third embodiment of the present invention.

[0128] Step S410, receiving paging configuration information sent by the second transmission node; wherein, the paging configuration information is sent by the first transmission node to the second transmission node.

[0129] Step S420, according to the paging configuration information, receive a paging message sent by the second transmission node.

[0130] The paging configuration information includes at least one of the following information: paging cycle, candidate time-frequency position, transport block size, modulation scheme, resource allocation, repeated transmission times, CP type of cyclic prefix, transmission mode and scrambling identifier.

[0131] According to the paging cycle and candidate time-frequency positions in the paging configuration information and the identif...

Abstract

The invention discloses a paging method, a paging device and a transmission node. When being executed at a first transmission node, the method comprises the step that the same paging configuration information and paging indication information are sent to at least one second transmission node. When being executed at the second transmission node, the method comprises the following steps that: the paging configuration information and paging indication information sent by the first transmission node are received; the paging configuration information is transmitted to a third transmission node; anda paging message is sent to the third transmission node according to the paging configuration information and paging indication information. When being executed at the third transmission node, the method comprises the following steps that: the paging configuration information sent by the second transmission node is received; and the paging message sent by the second transmission node is receivedaccording to the paging configuration information. With the paging method, the paging device and the transmission node of the invention adopted, the receiving energy of the paging message is improved,the same paging message coverage can be achieved with fewer paging resources used, and the coverage of paging can be maximized with minimum resources.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a paging method, device and transmission node. Background technique [0002] In order to meet the needs of Cellular Internet of Things (C-IoT for short), a new access system named NarrowBand-Cellular Internet of Things (NB-IoT for short) was held at the 69th plenary session of 3GPP Been proposed. Among them, the system focuses on low-complexity and low-throughput radio frequency access technologies. The main research goals include: improvement of indoor coverage, support for a large number of low-throughput user equipment, low delay sensitivity, ultra-low equipment cost, Low device power consumption and network architecture. In addition, in order to meet the needs of the fifth generation (5G) mobile communication, in the 3GPP organization, discussions have begun to be named as massive Machine Type Communications (mMTC for short) in the category of New Rad...
